Giant Amazing Cactus Flower

Last night I had an asthma attack brought on by allergies, and had to be rushed to the hospital by ambulance. It's only ever happened once before, about two years ago, but golly, the stuff they put into my oxygen mask was the weirdest thing ever! It was only Ventolin, but I went all Puff the Magic Manda from it and had to have 5 doses of the stuff before they'd let me leave the hospital. I sat there blowing smoke and giggling every time a huge dose of the stuff would rise from the mask.... once I'd already had 3 doses and could breathe again that is. We really don't take the ability to breathe seriously enough until something like that happens.

Look what opened its petals today. One of my giant cactus flowers.Isn't he a beaut? It's bigger than my hand, and yet the cactus itself is quite a small plant. Want a closer look?It has little hairs all over it that are silky smooth, and little ripples all the way through it. The bud is at first fully enclosed, and then bursts open into this amazing star shape. I don't know the name of it though, so if anyone does, please let me know, that would be wonderful!
Oh, did I mention, I can breathe again!!

I've finally discovered the name of this plant! It's commonly called Starfish Flower or Starfish Cactus. And it's scientific name is Stapelia grandiflora. It's actually a carnivorous plant!
If anyone is reading this, and they have the same plant, but a different coloured/patterned flower, then contact me, as I would love a cutting of it!
